generate_json_map now adds parsed display names

[tomkane-dls]

Updated _generate_json_map:

• display names are now taken from .bob files and added to the json map
• display_name = <name> tag if present, if not display_name = filepath tail without file extension, if not display_name = null (using _parse_display_name)
• if duplicate display names for children they are enumerated (cam 1, cam 2 etc.) (using _fix_duplicate_names)

Additionally:

• removed 'visited' logic and just traverse bob files multiple times if needed
• added more comments to _generate_json_map
• moved _get_macros from to flatten class
• commented out visited node test
• adjusted tests/example json with relevant display names or None so that they pass
